Ingredients
- Lemon cake mix: this shortcut gives the cake its punchy citrus aroma look for a brand with real lemon oil for best flavor
- Lemon pie filling: brings the tart jammy lemon layer it should be thick and glossy choose a brand with whole pieces of lemon if possible
- Unsalted butter: this coats the cake mix and adds rich flavor always use real butter for the best taste and color
- Powdered sugar: optional for dusting on top once baked it lends a little sparkle and balances tartness sift it for the prettiest finish
Step-by-Step Instructions
- Preheat and Prepare Pan
- Set your oven to three hundred fifty degrees Fahrenheit one hundred seventy five degrees Celsius Grease a nine by thirteen inch baking dish with butter or nonstick spray so nothing sticks
- Layer the Lemon Filling
- Spoon the entire can of lemon pie filling into the baking dish then use a spatula to spread it evenly to corners This ensures every bite is full of bright citrus flavor
- Top with Cake Mix
- Evenly sprinkle the dry lemon cake mix over the lemon pie filling Make sure to cover the filling entirely without big patches so the cake browns evenly
- Drizzle with Melted Butter
- Pour melted butter slowly all over the dry cake mix surface Move back and forth to moisten as much of the top as you can Any dry patches will end up crumbly instead of crisp
- Bake Until Golden
- Place the dish in your oven Bake for thirty five to forty minutes The surface should be golden brown and the edges bubbling with lemony goodness Check the center with a spoon to confirm the cake mix is set not wet
- Cool and Finish
- Once out of the oven let the cake cool for at least five minutes so the layers set and you can serve neat slices If using dust the top with powdered sugar right before serving

I cannot resist sneaking a corner piece the edges get extra golden Each time my mom visits she requests hers served with a scoop of vanilla ice cream and fresh lemon zest
Storage Tips
Let the cake cool completely before covering to prevent sogginess You can store it covered in the fridge for up to four days Reheat individual servings in the microwave for about twenty seconds for maximum gooeyness
Ingredient Substitutions
If you only have white or yellow cake mix add a teaspoon of grated lemon zest to mimic the lemony brightness You can swap lemon curd in for the pie filling just spread it gently so it is even And for a dairy free version use melted coconut oil in place of butter
